With the earlier version of Autopilot on the Mavic Pro, You could plan a mission with the starting point and the end point and it was pretty accurate. You could save the mission and use it over and over. The app was discontinued with the M2 Pro which did not make me happy. You could save a waypoint mission and do this. Not sure how accurate or consistant it would be for repeated missions though.
However, as mentioned above, there are many reasons not to do this. If you have a flight path to get to the destination without flying over people, say from the side, and you could manually fly it while maintaining VLOS, that would be the only way I would try this. But then it also sounds like there will be a lot crowded people including at the drop site. So again, it would be a big NO.
